This is really a problem that I have had since I installed F21. It was a clean install, not an update. Anyway, when I connect to various servers that are setup for user/paswd login, it is a while before I see the password prompt. After working on the system for a while, the session is suddenly unresponsive. I can ping the destination, but nothing in the ssh session. Usually after some time (more than a minute) the session resumes responding. If I leave a session connected and move away from it, eventually I get a "Write failed: Broken pipe" All the systems I am connecting to are on other networks, so I am going through a firewall that permits my ssh connections. Any hints where to look? Wireshark is not showing me anything, but I may just be using the wrong filters.
In my experience, a slow ssh password prompt is due to DNS lookup issues--particularly reverse DNS (ipaddr-to-hostname) lookups. If the remote machine is having trouble doing a reverse DNS lookup on your client IP, then you just have to wait for the DNS to time out before you get the password prompt. As to why it slows down, could be any number of other things. Are you on a VPN? Are you getting your IP via a DHCP server? Are you on a broadband connection? ---------------------------------------------------------------------- - Rick Stevens, Systems Engineer, AllDigital ricks@xxxxxxxxxxxxxx - - AIM/Skype: therps2 ICQ: 22643734 Yahoo: origrps2 - - - - This message printed using recycled bandwidth - ---------------------------------------------------------------------- -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
